Operating Mode; Operating Safety Devices; “G01 Water Missing”; “G02 Boiler Pressure Low” - Rancilio CLASSE 10 USB Technical Manual

6.2. Operating mode
Once the temperature/pressure is reached, the date,
the current time and the pressure data will stay on
display (for 20 sec.) and flash alternatively to the
customisation logos.
During dispensing, the following is displayed:
1 Coffee dispensing symbol
2 Hot water dispensing symbol
 iSteam dispensing symbol
4 Date and time
5 Selected coffee dispensing group
6 Hot water dispensing
7 Type of hot water blending (4-TEA)
8 Milk warm-up display
9 Milk instant-temperature
10 Boiler pressure
11 Cup heater symbol
12 Set-time symbol
1 Water charge symbol
14 Boiler resistance ON symbol
If one of the two time/doses control functions are
activated, the coffee symbol space will instead
display:
otherwise:
"Brewing time "
For energy saving purposes, the display will reduce
its luminosity after one hour of continuous inactivity
without dispensing anything. After two hours of con-
tinuous inactivity without dispensing anything, it will
switch itself off altogether.
7. OPErATING SAfETY DEVIcES
When the coffee maker is switched ON, it checks
whether there is enough water in the boiler.
7.1. If the water level is inadequate, the machine
tops up the level automatically. If this does not
take place within a set period, the boiler filling
operation is discontinued and a warning message
is displayed:
"G01 Water missing"
7.2. If the water presence check result is positive, the
boiler heating resistances are enabled.
If the set pressure is not reached within a specific
time, the power supply to the heating resistances
is cut off and a warning message is shown on the
display:
"G02 Boiler Pressure low"
7.3. If the safety device for slow dispensing interve-
nes, the LED of the dispensing button must flash
until the end of dispensing.
The boiler safety devices can be reset by switching
the machine OFF and then back ON again
8. THE cUP-WArmEr
By pressing the relative button, the display shows
the following:
Depending on the darkened segments it indicates the
selected power status of the cup-warmer resistances
(min – med – max – off).
passing from one level to the next is performed by
pressing on the cup-warmer key.
